Interpretation:The best synthetic routefor synthesis of methanolfrom simple alkane should be suggested and disadvantages of synthesis with
Concept introduction: The carbonyl bond is polar with the partial positive charge on carbon and partial negative charge on oxygen as illustrated below.
Grignard reagents are
Methyl bromide reacts with magnesium ether to give Grignard reagent. This Grignard methyl magnesium bromide on treatment with formaldehyde gives corresponding alcohol. The mechanistic pathway for the latter reaction is as follows:
The polar carbonyl bond breaks and the polar Grignard reagent attack at electron-deficient carbon. Finally with the hydrolysis and work up the alcohol is formed.

- Show the correct sequence to connect the reagent to product. * see imagearrow_forwardThe answer here says that F and K have a singlet and a doublet. The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forwardDraw the Birch Reduction for this aromatic compound and include electron withdrawing groups and electron donating groups. *See attachedarrow_forward
